DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door assembling trolley suitably used for connecting a hinge of a door to a hinge of a door frame and attaching the door to the door frame.

[0002]

2. Description of the Related Art When attaching a door (50) to a door frame (51),
In order to connect the hinge (53) of the door (50) and the hinge (54) of the door frame (51), conventionally, as shown in FIG.
1) is placed horizontally on a mounting surface such as a floor, and while the door (50) is supported by hand so that the width direction is the vertical direction, the door frame (5) is
A plurality of hinges (54) (54) attached to 1) and a plurality of hinges (53) (53) attached to the corresponding door (50) ...
And are connected respectively.

[0003]

In the prior art as described above, the hinges (53) and (54) must be connected while supporting the door (50) by hand so that the width direction is the vertical direction. As a result, the door (50) is heavy and requires multiple workers,
Poor workability. In addition, the hand is likely to be caught between the door frame (51) and the door (50), which is very dangerous.

Accordingly, an object of the present invention is to provide a door assembling trolley that can improve workability and prevent danger.

[0005]

According to the present invention, there is provided a door mounting base provided with a support leg standing on a bogie main body which can travel and travel by running wheels, and protruding horizontally from the support leg. In addition, the door mounting table has a width in which the door frame can be moved from the front end of the mounting table to the position close to the support leg portion so that the width direction becomes the vertical direction. The hinge at the upper end of the installed door frame and the hinge at the end of the door laid on the mounting table have opposite heights, and a door is connected to the lower side of the mounting table. With the hinge portion as a fulcrum, the lower end of the door frame has a space rotatable to a position where the door is fitted to the door frame, and the tip of the mounting table is also rotated as described above. The support member that supports the door frame A door assembly truck to.

Further, the present invention is characterized in that the door mounting table is fixed to the support leg so as to be vertically displaceable.

Further, the present invention is characterized in that the supporting leg is provided with a gripping member for gripping the bogie body when moving.

[0008]

According to the present invention, the door frame is moved from the tip of the door mounting table to the position close to the support leg portion so as to fit over the door mounting table, and is installed so that the width direction is the vertical direction. The door is laid down on the table, and the hinge at the upper end of the door frame and the hinge at the end of the door are connected to each other. afterwards,
With the hinge portion connecting the doors as a fulcrum, the lower end side of the door frame is rotated to a position where the door is fitted to the door frame, the support member is pulled out from the tip of the mounting table, and this support member is used. Support the pivoted door frame, in this state,
Move the cart body to the required location.

Further, since the door mounting table is fixed to the support legs so as to be vertically displaceable, it is possible to cope with a different standard, for example, a parent-child door.

Further, since the supporting leg is provided with a gripping member, the bogie main body may be moved by gripping the gripping member, which is convenient.
